Answer 1

Answer 2

These are the steps involved:

a. Add Na2CO3  

b. Stir  

c. CuCO3 is formed. Now add H2SO4  

d. Boil away H2SO4

Explanation:

• A simple way to separate CuSO4 from NaCl is to react the Copper Sulphate with Sodium Carbonate to get a blue precipitate of Copper Carbonate (CuCO3).  

• Copper Carbonate is highly insoluble in water. CuCO3 can be filtered off of the Sodium Chloride and Sodium Sulphate (made by the reaction between the NaCO3 and the CuSO4) and rejected.  

• Copper Carbonate should be washed numerous times. We can then dissolve the Copper Carbonate with low-grade Sulphuric acid (H2SO4), to regain the Copper Sulphate.
